How to Quote Joinery Work Accurately — Stop Leaving Money on the Table

Every joinery workshop owner has done it. You look at a job — a set of bespoke internal doors, say — and you quote from experience. You've made doors before. You know roughly what the timber costs. You factor in a few days of labour, add a margin that feels right, and send the quote. The client accepts. Three weeks later the job is done, the invoice is paid, and you move on.

Except you never checked whether you actually made money on it. You don't know if the hours matched your assumption. You don't know if the material cost crept up because you had to order an extra board of American white oak when the first one had a split you didn't spot until you'd started machining. You don't know if the finishing took a day longer than expected because the client changed the stain colour halfway through.

This is how joinery workshops slowly bleed profit. Not through catastrophic losses — through a hundred small underestimates that compound over twelve months.

Why gut-feel quoting fails

Gut-feel quoting works when every job is simple and identical. If all you make is standard pine window boards to the same specification, you can quote reliably from memory because the variables are minimal. But bespoke joinery is the opposite of minimal variables. Every project has different timber species, different finishes, different site conditions, different client expectations, and different hidden complications.

The problem with gut-feel is that it anchors to your best-case memory. You remember the straightforward version of a similar job — the one where the timber was clean, the measurements were right first time, and the installation went smoothly. You don't instinctively account for the reality that most jobs include at least one surprise, and surprises cost time and money.

Over dozens of projects, this optimism bias creates a pattern: you're always busy, always delivering good work, but your margins are thinner than they should be. You blame material price increases or slow-paying clients, when the actual cause is quoting based on what you hope a job will cost rather than what it actually costs.

The data you need to quote properly

Accurate quoting requires three numbers per job category: actual material cost, actual labour hours, and actual overhead contribution. Not what you think they were — what they measurably were.

When you have this data for twenty completed projects, you can quote the twenty-first with confidence. Not because you memorised the numbers, but because you can pull up a similar past project and see exactly what it cost. A set of oak internal doors last time used £1,400 in materials, took 38 hours of labour, and had a 12% waste factor on the timber. That's your starting point — not a guess, a measurement.

Breaking a quote into components

The most common quoting mistake is treating a job as one lump sum. "Those wardrobes will be about £8,000." That number came from somewhere in your head, but you can't defend it to a client who asks why, and you can't analyse it later to see if you were right.

Break every quote into components: materials, labour by phase, finishing, hardware, delivery, installation, and margin. Each component should have a number you can justify. Materials come from your supplier price list and your measured quantities. Labour comes from your hourly rate multiplied by estimated hours per phase. Finishing comes from the products specified and the surface area involved.

This isn't more work — it's different work. Instead of staring at a drawing and inventing a number, you're building a number from parts. And each part can be checked against your records from similar jobs. If you quoted 24 hours for assembly but your last three wardrobe projects averaged 32 hours, you know your estimate is low before you commit to it.

The hourly rate most workshops get wrong

Ask a joinery workshop owner their hourly rate and they'll give you a number — £35, £45, £55. Ask how they calculated it and most will admit it's what everyone else seems to charge, or what feels about right, or what they've always charged with inflation added on.

Your real hourly rate should cover: your wages, your employees' wages, workshop rent, machinery maintenance and depreciation, insurance, vehicle running costs, consumables, and a profit margin. Divide your total annual costs by the number of productive hours your workshop delivers per year — not calendar hours, productive hours. Deduct holidays, bank holidays, training, time spent quoting, admin time, and time spent fixing mistakes. The real number is usually higher than people expect.

If your actual cost to operate is £65 per hour but you're quoting work at £45 because that's what the competition charges, you're subsidising every project from your own margin. You might be winning work, but you're winning it at a loss. Getting your hourly rate right is the single biggest improvement most workshops can make to their profitability.

Building a quote library from completed projects

After you've completed and tracked twenty or thirty projects properly, you have something extremely valuable: a quote library. Not a spreadsheet of template prices — a body of evidence about what different types of work actually cost your workshop to produce.

When a new enquiry arrives for fitted bookshelves in painted tulipwood, you can look at your last three bookshelf projects and your last two tulipwood projects. You can see the real material costs, the real hours, and the real waste. You adjust for the specifics — the room is larger, the client wants adjustable shelves, there's restricted site access — and produce a quote grounded in data rather than optimism.

This changes the dynamic with clients too. When someone questions your price, you're not defending a guess. You can explain exactly where the number comes from. Materials cost this much based on current supplier prices. Labour takes this many hours based on your records of similar work. The finish adds this cost per square metre. It's professional, transparent, and it wins better work from better clients who value quality over cheapness.

Where software replaces the spreadsheet

You can track all of this on paper or in a spreadsheet. Some workshops do. But the reality is that paper systems don't get maintained under production pressure, and spreadsheets require a discipline that evaporates when you're three projects deep and the phone won't stop ringing.

Workshop management software like Joinery Core tracks material costs, labour hours, and project financials as part of your normal daily workflow — not as a separate admin task. When your team logs time against a project phase, that data feeds your job costing automatically. When you allocate materials from stock, the cost records against the project. At the end of a job, you have a complete cost breakdown without having done anything extra.

Over time, that history becomes your quote library. Every completed project is a data point for the next similar job. Your quotes get more accurate with every project you deliver, your margins stabilise, and you stop accidentally doing work at a loss.
